Autio got it right as far as the Bravia is concerned. I have a new one and we recently received word from Sony about the problem with the unit not turning off although ours hadn't acted up. The fix was very simple. Sony sent us a little USB device containing the software fix. Plug it in the USB port on the set and 30 seconds later the fix had been effected.
The Bravia is a really nice LCD tv in my opinion. I looked at a lot of tv's before deciding on the Bravia. I'm very happy with my decision to get it.
